I think we are all agreeing, there are a lot of variables that are going to make it an interesting trip to say the least! All the points are valid, lots of movement, chance of low light, dust, shooting from a vehicle, additional cost of fast glass. I think in the end, I would imagine you want to get the best shots possible to record a great trip. Expense is the key factor. I think we should all take a trip over there and put all of the theories into practice to be able to give the best advice the next time this question comes up. Now if we can just convince FOsteology to foot the bill....
